We present VLT spectroscopic observations with different spectral resolutions and different slit orientations of the two metal-deficient blue compact dwarf (BCD) galaxies Tol 1214–277 and Tol 65. The oxygen abundances in the brightest H ii regions of Tol 1214–277 and Tol 65 are found to be 12 + log O/H = 7.55 ± 0.01 and 7.54 ± 0.01, or Z⊙/24 . The nitrogen-to-oxygen abundance ratios in the two ...

a thermodynamic analysis of the counter flow wet cooling tower (cwct) in the steelmaking unit of the khuzestan steel company (ksc) is performed in this paper. we evaluated both energy and exergy formulations for analyzing the heat and mass transfer, exergy and second-law efficiency in this cooling tower. the lewis factor le f is an indication of the relative rates of heat and mass transfer in a...

Carboxylic acids may be metabolized to acyl glucuronides and acyl-coenzyme A thioesters (acyl-CoAs), which are reactive metabolites capable of reacting with proteins in vivo. In this study, the metabolic activation of tolmetin (Tol) to reactive metabolites and the subsequent formation of Tol-protein adducts in the liver were studied in rats. Two hours after dose administration (100 mg/kg i.p.),...

OBJECTIVE The first Phase I study of autologous tolerogenic dendritic cells (Tol-DCs) in Type 1 diabetes (T1D) patients was recently completed. Pancreatic islet transplantation is an effective therapy for T1D, and infusion of Tol-DCs can control diabetes development while promoting graft survival. In this study, we aim to systematically review islet allograft survival following infusion of Tol-...

The recombinant plasmid RP4-TOL was transferred into Caulobacter crescentus at a high frequency, and the plasmid was maintained for at least 50 generations. C. crescentus cells which contained RP4-TOL grew on all the aromatic compounds that the plasmid normally allowed Pseudomonas putida to grow on. Reciprocal transfers from C. crescentus donor to P. putida or Escherichia coli recipients were l...
